Use a compact core table
Start with five core columns and keep them mandatory for every entry.
- Date
- Mileage
- Maintenance action
- Provider
- Cost
Add optional diagnostic context
For recurring issues, short notes and attachments provide context that pure numbers cannot show.
- Symptoms before service
- Parts replaced
- Invoice photo or reference
Avoid over-engineering
If data entry takes too long, the system breaks. Keep the template lightweight and repeatable.
Move to a digital log when you need reminders, filters, and export.
